I'm hoping that this display will be usable with the ILI9488 driver on Picimite? 4" 480x320 LCD using ILI9488 chip It claims to use the same chip & is same resolution so in theory it will work, not sure about the touch though? |
||||||
I'll find out one day I just bought one. |
||||||
the link said £3.xx now says £23.xx other ad shows it £7.xx |
||||||
The link says £45.37 for the touch version here. Remember that on AE the price is shown without taxes and shipping though. Sometimes you have to spend £8 to get stuff in less than a month too!. |
||||||

||||||
For me, the link in the first post shows $12.76USD without touch, and $13.89 with--both including shipping. Why would the UK price be so high? |
||||||
I suspect the price you are seeing is the "First Time Discount" from that seller. When I clicked that link the price was $AU 12.xx for the touch version but jumped to $AU 21.27 + 10% tax when I logged in. Presumably I have bought from them before. |

Hi Bleep, AndrewG and I have been using these as our preferred LCD for well over 6 months now. They are exceptionally good. BTW the price shown for me is $19.54AU Regards, Mick. |
||||||
Mine cost A$23. Free postage Edited 2024-03-15 14:23 by palcal |

Ordered one yesterday. From the hint by Bleep on top of this thread. €16:50 incl VAT and postage. Good to hear that Mick has been satisfied. |
||||||
LOL! I was bog-eyed and thick-fingeredlast night.... The Price was (and still is) £4.37 for the touch version here. |
||||||
Hi, Aliexpress must almost make up the price on the fly! Every time I go there my price, without touch is £9.56, or £10.43 with touch, free delivery, but 20%VAT is added at checkout, so £12.48 for a touch version delivered, supposedly 7 day delivry! Yes I've ordered one to try. :-) Regards Kevin Edited 2024-03-15 20:22 by Bleep |

Mick, the big one, Does this screen still need the resistor diode mod to get it working properly, can someone point me to a definitive version of how to connect up this mod, a simple circuit diagram showing resistor & diode & what pins to connect to will be fine. Regards Kevin. |
||||||
Thing to remember about the ili9488. 1. They are slow 2. You need an extra resistor and diode to get reliable reading 3. They are slow 4. They are too big for both a framebuffer and a layer buffer to fit in memory 5. They are slow Reasons: The ILI9488 controller has a bug where it doesn't tri-state MISO properly hence 2 The ILI9488 does not support 16-bit RGB565 over SPI so all writes and all reads are 3 bytes per pixel The ILI9488 needs a much slower clock for reading pixels than any other display They only support H/W scrolling in portrait mode so use for a console is terrible. It takes about 1 second to scroll a line of text up the screen They have 2x the pixels of an ILI9341 and need 3 bytes per pixel vs 2 so things like CLS take 3x longer than on an ILI9341 Wiring mod Edited 2024-03-15 20:45 by matherp |

Hi Peter, I realise they are slow, :-( I want to use one as a console on a Picomite USB I like the 340x480 space, but it appears this is the only display of that resolution that can be used as a console, now that the 9481 is disabled, it looks like scrolling is very slow, but page up/down not too bsd, so I'll have to train myself to mainly use that. Thank you for the photo of the mod, that looks very simple. Regards Kevin. |
||||||
Is there any more suitable 480x320 SPI LCD which is supported (or could be)? I'm with bleep--if there's nothing better (of the SPI type), the ILI9488 is satisfactory. |
||||||
Kevin, don't want to digress but these 7 inch displays I paid £12.50 for. Sold as car reversing monitor. got hdmi, vga and composite video... not avi as advertised- no audio- no speakers. says 5V to 24V supply but need 2A 5V. 12V 1A ok vga 640x480 and pico is readable and scrolls as vga does. uses little space. use with a small usb keyboard makes a small system.. no touch screen or sd card slot though. just a suggestion. stan |

||||||
Ok thanks Peter, it looks like I'll have to try to build one of your 1963 parallel USB boards, or find a nice small bare VGA display to use with a VGA USB board. Regards Kevin. |
||||||
these vga displays are take to bits able but why. the base is standard tripod mount. small case border |
